I always do a CLEAR PRGM but still happens

Wait a minute. You press f CLEAR PROGRAM, i.e. [f] [CLX], in PRGM mode (!) and the program is not cleared?
Check this: Press RTN, switch to W/PRGM and press f CLEAR PROGRAM. You will see "00 00".
Press SST. If you now see "23" program memory indeed has not been cleared.
If you see "35 01" the default programs have been successfully deleted.

If this is what happened the results are 0,03 and 7,07 which are the two-digit rounded values for 1/40 = 0,025 and √50 = 7,0710678... This would also explain the "weird results" you mentioned if the C key is pressed – by default that's the y^x power function which operates on both X and Y.
